Miami is 1 hour behind São Paulo
Best overlap: 9:00 AM to 6:00 PM in São Paulo is 8:00 AM to 5:00 PM in Miami.
Your window to reach both cities is 9:00 AM to 6:00 PM in São Paulo, which converts to 8:00 AM to 5:00 PM in Miami. A 9-hour overlap gives you real choice here — early or late in the window both work comfortably. A quick caveat — Miami's clocks move for daylight saving and São Paulo's don't, so the times here are right for only part of the year.
